双磁光阱的同步实现是利用冷原子干涉仪检验爱因斯坦等效原理的重要实验基础之一。采用高频声光调制移频方案获得了冷却囚禁85Rb 和87Rb两种原子的激光，进而同步实现了两种原子的磁光阱。在此基础上，研究了双磁光阱中原子数与冷却光参数的关系，优化了实验参数， 双磁光阱中两种原子的数目均达到109。

Synchronous realization of two magneto-optical traps is one of the fundamental technologies of testing Einstein’s equivalence principle by using atom interferometers. High frequency acousto-optic modulators were used to achieve the lasers for trapping 85Rb and 87Rb simoutaneously, and a dual magneto-optical trap of 85Rb and 87Rb was realized. Based on the dual magneto-optical trap, the dependence of atom numbers in the dual magneto-optical trap on parameters of cooling laser were investigated, and optimized experimental data were obtained. The number of both species reaches to 109 in the dual magneto-optical trap.
